Description

The LT®1316 is a micropower step-up DC/DC converter that operates from an input voltage as low as 1.5V. A programmable input current limiting function allows pre- cise control of peak switch current. Peak switch current can be set to any value between 30mA and 500mA by adjusting one resistor. This is particularly useful for DC/DC converters operating from high source impedance inputs such as lithium coin cells or telephone lines.

The fixed off-time, variable on-time regulation scheme results in quiescent current of only 33µA in active mode.Quiescent current decreases to 3µA in shutdown with thelow-battery detector still active.

The LT1316 is available in 8-lead MSOP and SO packages.
